Abstract:
Objective To compare the clinical outcomes of 2 different catheter ablation strategies for patients with chronic atrial fibrillation(CAF).Methods One hundred and thirty four consecutive patients(77 males,mean age 56.8?12.3 yrs)were randomized into 2 groups of different catheter ablation strategies.All the patients suffered from frequent attacks(more than 3 times per month),drug refractory and symptomatic CAF.One group received circumferential pulmonary rein ablation(CPVA group,n=68)and the other group received complex fractionated electrogram ablation additional to CPVA(CPVA+CFEA group,n=66).All ablation was guided by 3 dimensional mapping system(CARTO).Follow-up ECG,Holter and clinical outcomes of the 2 groups within 6 months after the procedures were analyzed.Results The baseline characteristics were comparable between the 2 groups.The mean procedure time in the CPVA+CFEA group was longer than that in the CPVA group but the mean fluoroscopy time between two groups had no significant difference.After the first procedure,60%of patients in the CPVA group and 77% of patients in the CPVA +CFEA group were free from symptomatic atrial tachycardia without any use of antiarrhythmic drugs for at least 3 months(P
